Look back over history, people have put their lives at stake to go out and explore. We believe in what we’re doing. Now it’s time to go.” We, at Northdonning Heedwell believe that the time has truly come – the time to explore. „Arshia‟, which means heavenly in Sanskrit, is an embodiment of our commitment towards our goal, our belief. Proposed for completion in 19 years, Arshia will be located in the Asteroid belt, which provides myriad lucrative mining opportunities. Northdonning Heedwell chooses the S-type asteroid 6-Hebe as its mining target, which shall provide valuable minerals, required not only for construction but also for manufacture of other goods and commodities. Northdonning Heedwell keeps the following objectives in mind, to ensure the Foundation Society‟s enduring success: To design the structure keeping in mind that along with the advantages of remaining in orbit, the settlement also faces a multitude of risks from high velocity dust particles as well as meteorite and asteroid collisions. The entire structure has therefore been shaped accordingly to provide minimum drag. To create Differential Gravity Zones to maximize efficiency and utilize every bit of available volume. Space allotment has been done in such a way that agricultural and industrial sectors never prove to be visual nuisances to the citizens of Arshia, while providing them natural views of space at every given point of time. To automate most operations on the settlement to reduce manual labor and to provide facilities for entertainment, recreation and employment to all citizens. To make Arshia a self-sustaining, mine-to-manufacture unit that generates its own resources such as food and consumer goods required by the citizens, by means of aeroponic agriculture and industries. To secure Arshia‟s position as a pioneer in mining, shipping and an economic gains hub in the Asteroid Belt, to achieve our ambition of exploring the unexplored. Innovation, practicality, profit and comfort are characteristic attributes of all Northdonning Heedwell models, and Arshia shall be no exception. Northdonning Heedwell welcomes you to Arshia, a “Home Away from Home”. STRUCTURAL DESIGN 4 2.0 STRUCTURAL DESIGN Arshia is a one of its kind space settlement whose structure provides a break from the much propagated toroidal structure. Northdonning Heedwell introduces the concept of 5 different gravity zones due to the unique structure comprising of concentric cylinders. The structure of Arshia draws inspiration from the streamlined shape of an airplane fuselage, to minimize the drag associated with cosmic dust, hence the ends of the cylindrical structure have hemispherical nozzles. 2.1 EXTERNAL DESIGN Fig. 2.1 Dimensions of main components 2.1.1 EXTERNAL DIMENSIONS AND FUNCTIONS Residential & 2 Special 1g 2 Nozzles Agricultura Industrial COMPONENT Central Shaft Commercial Areas (Ozzy 1 & Ozzy 2) l (AgroCyl) (CylInd) (ResCom) (Geocyl) SHAPE Hemispherical nose Cylinder Cylinder Cylinder Cylinder Cylinder RADIUS (m) 350 100 200 350 450 75 LENGTH (m) 350 each 500 500 500 500 50 VERTICAL Variable 200 90 140 90 140 CLEARANCE (m) BASE SURFACE 769,300 each 314,000 628,000 1,099,000 1,409,075 35,325 AREA (m2) VOLUME (m3) 89,751,666 each 15,700,000 43,803,000 123,088,000 128,740,000 1,766,250 GRAVITY 0g 0g 0.4g 0.7g 0.9g 1g RATE OF - - 1.33rpm 1.33rpm 1.33rpm 1.33rpm ROTATION Partially - 13.47 psi - 13.2 psi 13.2 psi PRESSURISATION pressurised .Attached to the .Main Houses all Houses all .Housing .Observatories two ends of the stationary agricultural refineries for .Offices & .Education central shaft to component activities mineral Shops center minimize drag that supports a (aeroponic processing as .Administrati .Communicatio while in orbit, and nozzle at each chambers, well as ve centers n antenna in the process, of its two ends processing storage. .Public .Recreational FUNCTION minimize wear .Primary units and spaces & snow park and tear Control Unit food Recreational .Main ports and .Power Station storage) activities docking stations .Transportati- .Detachable on between volumes in case of various emergencies facilities Table 2.1 Dimensions and Functions of Main Components 5 2.1.2 CONSTRUCTION MATERIALS Arshia makes skillful use of the materials required in its construction, which are acquired from the moon, Mars and 6- Hebe itself. This saves the expense of carrying material from Earth against high gravity. The entire structure can be divided into three main parts in terms of the construction material - Transparent glass parts, non-transparent hull components and the Pneumatic Chamber Shield (PCS) (Fig 2.2). The hull components are all fabricated in the form of the interlace, a structural innovation whereby the hull is made capable of enduring maximum stress. This is done in the form of two layers of tubings, one of NI-Fe alloy and the other of Titanium alloy, spiraling in opposite directions, hence creating a mesh, radically increasing the structural integrity of Arshia. Natural views of space are provided from the two ends of the cylinder, where electrochromic glass is used to provide the day and night cycle. These large transparent, well shielded structures serve as windows to the outside world.

    2001 ANNUAL REPORT DuPont at 200 In 2002, DuPont celebrates its 200th anniversary. The company that began as a small, family firm on the banks of Delaware’s Brandywine River is today a global enterprise operating in 70 countries around the world. From a manufacturer of one main product – black powder for guns and blasting – DuPont grew through a remarkable series of scientific leaps into a supplier of some of the world’s most advanced materials, services and technologies. Much of what we take for granted in the look, feel, and utility of modern life was brought to the marketplace as a result of DuPont discoveries, the genius of DuPont scientists and engineers, and the hard work of DuPont employees in plants and offices, year in and year out. Along the way, there have been some exceptional constants. The company’s core values of safety, health and the environment, ethics, and respect for people have evolved to meet the challenges and opportunities of each era, but as they are lived today they would be easily recognizable to our founder. The central role of science as the means for gaining competitive advantage and creating value for customers and shareholders has been consistent. It would be familiar to any employee plucked at random from any decade of the company’s existence. Yet nothing has contributed more to the success of DuPont than its ability to transform itself in order to grow. Whether moving into high explosives in the latter 19th century, into chemicals and polymers in the 20th century, or into biotechnology and other integrated sciences today, DuPont has always embraced change as a means to grow.

  • 2016 Soy Products Guide Soynewuses.Org / Thinksoy.Com the Use of Soybean Derivatives in Manufacturing Isn’T New
    2016 Soy Products Guide SoyNewUses.org / ThinkSoy.com The use of soybean derivatives in manufacturing isn’t new. In fact, Henry Ford and George Washington Carver shared a vision in using soybean and other natural derivatives to make plastics, paint, fuel and other products. In 1942, Ford built a car with a plastic body made from soybeans and posed in front of it in a suit made of soy-based fiber. The United Soybean Board (USB) is carrying on this vision by supporting innovative soy-based research for new product development. Since the mid-1990s this ongoing research has led to the development and manufacture of more than 800 products that contain soy, including soy- based spray foam insulation; plastic composites for cars, boats and agricultural equipment; paint; ink; and wood adhesives used in plywood, hardwood and particleboard. The list grows every year with new products. As global demand for fuels, fiber and material continues to climb, soy-based products and feedstock provide smart, sustainable alternatives to petrochemical-based products. With equal, or better performance, and lower environmental impact, soy-based products make it easy to go green. Think of all the ways you can save when you Think Soy.

J O Y C E Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1983 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. ELMER KEISER BOLTON June 23, 1886-Jidy 30, 1968 BY ROBERT M. JOYCE LMER KEISER BOLTON was one of the outstanding leaders E of industrial research. He became an industrial re- search director at a time when research was only beginning to be a significant factor in the chemical industry. There were no models for this new role, and Bolton's concepts of direct- ing industrial research were in large measure those that he formulated himself, reflecting his vision and drive to achieve important commercial goals. The record of industrial products developed by Du Pont research organizations that he directed is impressive; it in- cludes synthetic dyes and intermediates, flotation chemicals, rubber chemicals, neoprene synthetic rubber, nylon synthetic fiber, and Teflon® polytetrafluoroethylene resin. His leader- ship in bringing these developments to fruition was always apparent to management and to those he directed, but be- cause of his characteristic self-effacement his name is not widely associated with these accomplishments. Throughout his career he supported and encouraged his technical person- nel. Most important, he had the knack of picking the right time and direction to take in moving a research lead into development. Many of his decisions proved crucial to the ultimate success of these ventures.

  • Ball Valve Seat/Seal Materials and Service Applications
    APPLICATIONS - VALVE SOFT SEAT/SEAL MATERIALS One of the most important factors affecting shutoff capability is the nature of media being handled. Service life is affected by all of the following factors: - pressure, temperature, degree of pressure fluctuation and thermal fluctuation, type of media, cycling frequency, velocity of media & speed of valve operation. The following seat & seal materials can be used in various valves such as ball, plug, butterfly, needle, etc. BUNA-N (HYCAR or Nitrile) - Buna-N is a general-purpose polymer which has good resistance to oil, water, solvents and hydraulic fluids. It also displays good compression, abrasion resistance, and tensile strength. This material performs extremely well in process areas where paraffin base materials, fatty acids, oils, alcohols or glycerins are present, since it is totally unaffected. It should not be used around high polar solvents (acetones, ketones), chlorinated hydrocarbons, ozone or nitro hydrocarbons. Temperature range is 107°C maximum. Hycar is black in colour and should not be used where discolouration cannot be tolerated. It is regarded as a comparable replacement neoprene. Major differences are: Buna-N has a higher temperature limit; neoprene is more resistant to oils. EPDM - EPDM is a terpolymer elastomer made from ethylene-propylene diene monomer. EPDM has good abrasion and tear resistance and offers excellent chemical resistance to a variety of acids and alkalines. It is susceptible to attacks by oils and is not recommended for applications involving petroleum oils, strong acids, or strong alkalines. EPDM should not be used on compressed air lines. It has exceptionally good weather aging and ozone resistance.
